Garlic. While you don't snack on it, garlic is extraordinarily versatile and, like its humble cousin the onion, shows up in virtually every type of cuisine in the world. It adds flavor, texture, complexity, and depth to countless recipes.
I have two favorite fruits; blueberry and orange. I love both of them just about equally. Whenever we have oranges, I end up eating most of them. I also love orange-flavored beverages and ice cream. My favorite vegetable would be the potato (I'm pretty sure it's a vegetable). I love mashed potatoes, baked potatoes... Sweet potatoes are probably the only potato product I don't like.
